Title: Innovations of Tatsuo Masumi
Introduction
Tatsuo Masumi is a notable inventor based in Amagasaki, Japan. He has made significant contributions to the field of liquid crystal technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Optical writing type liquid crystal light valve and writing apparatus." This invention features a liquid crystal light valve that includes a photoconductive layer situated between a pair of electrodes and a liquid crystal layer. The resistivity of the photoconductive layer is reduced in areas exposed to light, allowing for the application of voltage between the electrodes. This process enables the writing of image data by altering the crystalline structure of the liquid crystal layer in the illuminated areas. The design incorporates a laminate of an amorphous silicon film and an inorganic insulating film, which effectively suppresses carrier injection from the electrode to the amorphous silicon film. The voltage polarity for writing image data is inverted during horizontal scanning, facilitating the writing of black portions on a white background and vice versa. This method allows for efficient data writing and erasure, minimizing writing errors caused by stored charges.
